Definitions

  • the invention relates to a magazine for receiving insertable electrical assemblies, which are held in guide rails which rest against U-shaped carriers extending transversely to these.
  • the recesses are arranged evenly distributed along the carrier in accordance with the assembly division.
  • the beams are made of flat material and are provided with recesses throughout before bending. In this condition, they are made available by the meter and cut to length depending on the magazine width.
  • the recesses for receiving the guide rails are designed as sawtooth-like notches on the side edges and as openings on the bending edges of the carrier.
  • individual support plates are arranged parallel to each of two assemblies and attached to the supports.
  • openings are provided, corresponding to the cross section of the supports, through which the supports are inserted.
  • the lateral fixation of the support plates takes place by means of a connecting piece which is screwed onto the support plate and engages in one of the recesses in the carrier.
  • the ends of the carriers are attached to side plates of the magazine. They have projections on their end faces, which engage in corresponding openings in the side plates.
  • the U-shaped supports have openings in the side legs, into each of which a plug nut is inserted. This plug nut is clamped to the side plates of the magazine by means of a screw, as a result of which the carrier is securely held on the side plate. Even before bending the carrier, the openings for the plug nuts and the front projections z. B. formed by stamping.
  • the guide rails for the modules have a groove-shaped guide track. On the side facing away from the guide groove, rigid nose-like projections of the guide rail project into corresponding recesses in the carrier and engage behind them. When installing the guide rails, they must be moved lengthways. In its end position, the guide rail is secured by a stop.
  • the invention has for its object to simplify the manufacture of the assembly frame and its assembly.
  • the design of the projections makes it possible to cut the carrier to length in the region of the recesses in a simple cutting process, as a result of which the projections result automatically. Due to the hole-shaped design of the recesses in the side legs of the carrier, it is possible to use a correspondingly adapted plug nut without having to form additional openings. This means that apart from separating, no additional work step is required to train the wearer.
  • the carrier can in the unbent state or in the bent state z. B. separated by sawing. In this case it is possible to deliver the bar material in the bent state.
  • the development according to claim 2 ensures that the guide rails can be attached to the carriers with a simple linear movement.
  • the locking hooks protrude in the direction of the recesses and are laterally deflected when they are inserted into them. In the end position, they spring back and reach behind the straps.
  • the locking hooks are deflected perpendicular to the direction of extension of the guide rails. Since two locking hooks spring against each other at the same time on a guide rail, the lateral spring forces cancel each other out. This prevents the guide rail from tipping or twisting during assembly. Due to the hole-shaped configuration of the recesses and by adapting the latch hook width to the corresponding dimension of the recess, it is possible to fix the guide rail to the carrier not only in the transverse but also in the longitudinal direction.
  • the guide rail must be bent so far during insertion and removal that its stop surface can slide past the corresponding counter stop surface of the carrier. This bending requires some dexterity, since there is a risk of breakage if the bending is too strong, and because unlocking or locking can fail if the bending is weak.
  • the development according to claim 5 makes it possible to release the latching in the recesses by simply compressing the guide rail in the region of the longitudinal slot.
  • the development according to claim 7 ensures that the support plates can now be attached directly to the carriers. There is no need for time-consuming screwing and connecting pieces for fastening to the brackets.
  • the support plate is z. B. with a side edge on the carrier. The extensions from this side can te go out, are inserted through the associated hole-shaped recess in a simple manner and engage behind the carrier with the side lugs. These are pressed resiliently against the engaging side wall of the opening and thereby secured in their position in relation to the carrier.
  • side lugs on both sides of the opening on an extension. The lugs pointing in the same direction encompass the side wall of the opening on both sides.
  • the height of the protrusion is dimensioned such that it can first be inserted deeper into the opening than is required for fixing.
  • all extensions on the top of the support plate are formed in this way. This makes it possible to first insert the upper extensions of the initially inclined support plate into the openings in the upper supports so deep that the shorter lower extensions are located above the lower supports. These are then inserted into the corresponding lower openings until the lower edge of the support plate sits on the lower support. In this position, the longer upper projections still protrude through the openings in the upper beams.
  • the width of the openings is greater than the height of the side lugs of the extensions plus the thickness of the support plate.
  • the pressure springs can be inserted or removed successively. They can be designed as simple wire brackets which are resiliently clamped between the other side wall of the opening and the extension of the support plate. The pressure springs can be inserted and removed in a simple manner without additional aids.
  • the insertable electrical assemblies 1 can be connected via backplane connectors 2 by means of backplane wiring.
  • This backplane wiring has a printed circuit board 3 which extends over the entire magazine backplane.
  • the assemblies 1 are held in guide rails 4 which are fastened to horizontal, rod-shaped supports 5 which extend perpendicularly to them. These are attached to their end faces by means of fastening screws 6 on side plates 7 of the magazine.
  • the U-shaped support 5 is continuously provided with grid-like recesses 8 in the form of rectangular holes. These recesses 8 are arranged in pairs in the side legs of the carrier 5. At its end, this is cut off approximately in the middle of one of the pairs of recesses.
  • projections 9, 13 are thus formed on the end faces of the carrier 5 at this point.
  • the carrier 5 is firmly connected to the side plate 7 at its end.
  • the projections 9 protrude into corresponding openings 10 in the side plate 7.
  • a flat plug nut 11 is inserted into the adjacent pair of recesses.
  • the fastening screw 6 is screwed firmly into the plug nut 11 from the outside of the side plate 7 and thus pulls the carrier 5 against the side plate 7. This ensures that the projections 9 cannot be pulled out of the openings 10.
  • the guide rail 4 is provided with a longitudinal groove 12 in which the circuit board edge of the assembly 1 (Fig. 1) is guided.
  • the guide rail 4 is fastened to the carrier 5 of the assembly magazine, indicated by dash-dotted lines. It lies on one of the side legs of the carrier 5. It has two latching hooks 14 in this area, which protrude through two adjacent recesses 8 of the carrier 5 and engage behind the relevant side leg of the carrier 5 with side lugs 15.
  • the latching hooks 14 are arranged symmetrically with respect to the central axis of the longitudinal groove 12 of the guide rail 4.
  • the lateral lugs 15 are arranged on the outer sides of the latching hooks 14 facing away from one another.
  • the guide rail 4 has a central longitudinal slot 16 in the area of the latching hooks 14, which extends between the two latching hooks 14. This forms two relatively schma on the guide rail 4 le flexible longitudinal webs 17, which carry the locking hooks 14.
  • the locking hooks 14 When inserted into the recesses 8 of the carrier 5, the locking hooks 14 are laterally deflected. This deflection is transferred to the longitudinal webs 17 in such a way that the latching hooks 14 can be made rigid and therefore very compact.
  • the two adjacent locking hooks 14 are resiliently clamped between the outer walls of the two adjacent recesses 8 facing away from one another.
  • the length of the latching hooks 14 in the direction of extension of the guide rail 4 corresponds to the length of the recesses 8.
  • the length of the guide rail 4 is thus precisely fixed in relation to the carrier 5.
  • the guide rail 4 can be used both for the upper and for the lower guide of the assembly 1. Since a recess 8 is provided for each of the two latching hooks 14, there is a finer subdivision for the recesses 8 along the carrier 5, which enables greater variability in equipping the assembly magazine with assemblies 1 of different widths.
  • FIG. 7 shows a support plate 18 for mechanical stabilization of the assembly magazine.
  • the support plate 18 is arranged between the assemblies 1 (FIG. 1) and extends parallel to these. It is firmly connected to the carriers 5. These serve both to fasten the guide rails 4 for the assembly 1 and to receive the support plate 18.
  • This has extensions 19, 20 on its side edges, which protrude into the recesses 8 in the carrier 5.
  • the extensions 19, 20 are provided with laterally shaped retaining lugs 21, 22. They rest on the side of the side retaining lugs 21 and 22 on the corresponding inner wall of the respective recess 8. They are held in this position by pressure springs 23 which are blown into the recesses 8.
  • the retaining lugs 21 reliably engage behind the side leg of the U-shaped support 5 facing the support plate 18.
  • the extensions 19 and 20 have a different height.
  • the lower edge of the support plate 18 rests on the lower supports 5.
  • the upper extensions 19 are so long that there is a distance between the upper edge of the support plate 18 and the upper supports 5 which is greater than the height of the lower extensions 20. This makes it possible to install a support plate 18 even after the assembly magazine has been completed .
  • the additional lateral holding lugs 22 of the upper extensions 19 have approximately the same height as the holding lugs 21.
  • the side leg of the upper carrier 5 facing the support plate 18 is encompassed by the two holding lugs 21 and 22.
  • the length of the extensions 19 and 20 is adapted to the length of the recesses 8 in the carriers 5, so that the mutual position is also fixed in this direction.
